Abstract
A start of packet detector comprises an input which receives start of packet information. The detector has a first stage which determines if there is a match between a respective subset of received start of packet information with a respective subset of reference start of packet information. The first stage repeats the determining for each of the subsets of received start of packet information and said respective subset of reference start of packet information. An output will provide a start of packet detected output which is dependent on the determining of the first stage.
Claims13
A start of packet detector comprising:
- an input configured to receive input data comprising start of packet information;
- a first stage configured to determine if there is a match between a respective subset of received start of packet information with a respective subset of reference start of packet information, said first stage being configured to repeat said determining and for each of subsets of received start of packet information and said respective subset of reference start of packet information, wherein a value of a counter is changed if there is a match between a respective subset of received start of packet information with a respective subset of reference start of packet information;
- and
- an output configured to provide a start of packet detected output, said start of packet detected output being dependent on a comparison of a value of said counter with a threshold.
A method of detecting a start of packet, comprising:
- receiving a first subset of received start of packet information;
- comparing the first subset of received start of packet information with a respective first subset of reference to determine if there is a match;
- changing a value of a count if a match is determined;
- repeating said receiving and comparing for subsequent subsets of received start of packet information and respective subsets of reference start of packet information;
- and
- providing a start of packet detected output dependent on comparing the value of said count with a threshold.
